In the last years, zeolites have been researched for a variety of agricultural and environmental applications because possess unique properties: cation-exchange, adsorption, and molecular sieving. Zeolite can be used as soil conditioners, amendments, remediation agents in contaminated soils with heavy metals et all. Because commercially zeolites are expensive the researches have as objectives synthesis of new materials from different materials. These materials are raw or wastes, for example power plant ash, and can to be used effectively in soil applications if understand effects of these in soils or soil-like systems.The aim of this study is synthesis and characterization of zeolitic materials synthesized from power plant ash. Two different zeolite materials, rich in zeolite phases, K–cabazite were obtained from power plant ash, using 3 M KOH solutions at atmospheric pressure, temperature below 90°C and contact time of 4 and 8 hours.New materials were analyzed for their composition and properties. The synthesized products provide a significant increase of CEC (cation exchange capacity) and the high ability to adsorb heavy metal ions (over 39 mg gí1). Because synthesized materials have high cation -exchange capacities that can be used as cation-exchange in a soil. The high cation-exchange capacities determined several researches for using of materials for lead and copper removal from soil.
